Public predicates

parse/2

Parses Base85 (Ascii85) data from the given source (atom(Atom), chars(List), or codes(List)) into a list of bytes.

Compilation flags:

static

Template:

parse(Source,Bytes)

Mode and number of proofs:

parse(++compound,--list(byte)) - one_or_error

Exceptions:

Source is a variable:

instantiation_error

Source is neither a variable nor a valid Base85 source term:

domain_error(base85_source,Source)

Source contains Base85 data with characters outside the Base85 alphabet:

representation_error(base85)

---

generate/2

Generates Base85 (Ascii85) in the representation specified in the first argument (atom(Atom), chars(List), or codes(List)) for the list of bytes in the second argument.

Compilation flags:

static

Template:

generate(Sink,Bytes)

Mode and number of proofs:

generate(+compound,+list(byte)) - one_or_error

Exceptions:

Sink is a variable:

instantiation_error

Sink is neither a variable nor a valid Base85 sink term:

domain_error(base85_sink,Sink)
